Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

7.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Cells Coordinate Growth and Proliferation02:36

Cells Coordinate Growth and Proliferation

5.2K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

4.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

8.2K
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

10.7K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

Negative Regulator Molecules01:23

Negative Regulator Molecules

38.7K
Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.

Summary

Growth factors typically promote cell movement. However, new research reveals that growth factor signaling can also trigger repulsive signals, guiding cells away from certain areas.

Area of Science:

  • Cell biology
  • Developmental biology
  • Molecular signaling

Background:

  • Growth factor signaling is traditionally associated with promoting cellular growth and motility.
  • The precise mechanisms governing cell migration and guidance in developmental processes are complex and continually being elucidated.

Purpose of the Study:

  • To investigate the potential role of growth factor signaling in mediating repulsive cellular responses.
  • To challenge the conventional understanding of growth factor functions in cell behavior.

Main Methods:

  • The study by Yoon et al. (2017) likely involved experiments to observe cellular responses to specific growth factors.
  • Analysis of signaling pathways activated by growth factors was probably employed.

Main Results:

  • The research uncovered evidence that growth factor signaling can directly induce repulsive cues.
  • This finding suggests a dual role for growth factors in directing cell movement, both attractively and repulsively.

Conclusions:

  • Growth factor signaling is not solely a promoter of cell attraction and motility.
  • These findings introduce a novel concept of growth factors actively repelling cells, adding complexity to developmental signaling.
